Among them, the core AD biomarkers in CSF, i.e., the 42 amino acid isoform of amyloid beta (Aβ42), phosphorylated tau (p-tau) and total tau (t-tau) [85], have been largely explored also for DLB as Aβ plaques and neurofibrillary tangles (NTFs) were detected in approximately 40% of patients with PD, PDD and DLB at autopsy [86]. Here, MAPT is linked to Lewy body dementia.
